Add better support for keyboard shortcuts. I use firefox every day and I still prefer it to chrome because it has better keyboard shortcuts, but they could be better still. 1. I can't disable Ctrl-P/Cmd-P that maps to print screen. I use emacs and this conflicts with many shortcuts that I am used to using. The print dialog takes a full second to display. I haven't had a printer in 8 years. 2. Firefox gives webpages more extensive key capture capability then chrome. Some pages take away the ability to press Ctrl-L to get to the firebug console, this requires me to use a mouse. It's slow. 3. I don't know how to setup a key mapping to change the zoom style.
